What new territory?
Are you implying we're about to go to war with a direct neighbor who actually has a modern military?![]()
America couldn't hold afghanistan or iraq but you have some americans think they could Canada the largest country by land mass. The smartest nation in the world that even if 1% fought back that's 400,000 people insurgency that look and speak just like you right on the largest unmanned border in the world. We speak the same language, immerse in the same culture, no way to distinguish a canadian walking amongst you saying allah akbar in mall of america. Americans are used to fighting wars overseas where the common american feels nothing or worries about threats now it would be at your door.
The border between the United States and Canada is the world's longest undefended border. It stretches for nearly 9,000 kilometers across land and water.
